Nightrider: Mit wBb6 und wBf3 scheint alles in Ordnung zu sein, doch um den Preis eines spürbaren Verlustes an konstruktiver Eleganz. (2022-04-04)

Korrekte Version: Lb5>f1 & Sg6>e5 (Gustav 4.1c C+)
SBD: Cooked, 1. Bxc6+ also leads to a position in which hxg2/Bxg2 mate will be forced, dualized.

Best solution seems to be Bb5-f1, Sg6-e5. Then 1. Sg6! is the key. Not tested with a brute force mode, though.

An excellent problem that deserves to be rescued. (2009-04-11)
